美国大规模调查华人血样DNA
文/江南独立记者
(邮箱:d*******[email protected],欢迎对此事关注的人士提供线索、建议或帮助)
在美国洛杉矶华人聚集区之一的蒙特利公园市,一项眼科健康调查(CHES:CHINESE
AMERICAN EYE STUDY)正在华人社区中展开。
奇怪的眼科检查
在美国定居多年的华人王丁(化名)参与了这项调查,现在他开始为这个调查感到百思
不得其解:“说检查眼睛为何要获取我的血样和DNA?”。
这一切要从9月说起,王丁当时接到CHES工作人员的电话,征询他是否愿意参加这项眼
科健康调查计划。60多岁的王丁眼睛不太好,当他看到这样的免费服务,而且又是当地
一家有名的眼科医院检测,他满口答应下来。
在当地,眼科检查至少要收取65美元的挂号费,如果再加一些眼科治疗,费用可能在几
百美元甚至上千美元,王丁说:“CHES不仅不收费,而且还承诺25美元的车马费。”对
很多像王丁这样的普通华人来说,这是一个诱惑。
王丁在电话里答应检查后,调查组的工作人员来到王丁的家里,对王丁的年龄、遗传病
史、疾病既往史、赴美时间等详细信息一一记录,这些资料都被输入到工作人员随身携... 阅读全帖

Chinese death rate is 7 per thousand, while birth rate is 12 per thousand.
How on earth would population drop dramatically when birth rate is over 50%
higher than death rate? The death rate would have to nearly double to even
have stable population.
The only causes for the kind of dramatic drop in population you described
would be famine, disease, or war. And all of them are commonly caused by

Bat cave solves mystery of deadly SARS virus — and suggests new outbreak
could occur
Chinese scientists find all the genetic building blocks of SARS in a single
population of horseshoe bats.

Mathematical models offer one form of clarity. When just 50% of the
population wears masks, say researchers simulating outbreaks, the share of
the population infected by the virus is cut in half. Once 80% of the
population wears a mask, it theoretically stops an outbreak in its tracks. &
ldquo;Any type of general mask use is likely to decrease viral exposure and
infection risk on a population level, despite imperfect fit and imperfect
adherence,” notes a 2008 study by the Netherland&rsqu... 阅读全帖

来自主题: QueerNews版 - OP-ED: Is It A Choice? A Scientist's View
When Tim Pawlenty said the science was "in dispute” about whether being gay
is genetic, that sure came as surprise to molecular biologist Dean Hamer.
By Dr. Dean Hamer, op-ed contributor
In a recent interview, Tim Pawlenty was asked “Is being gay a choice?” The
presidential hopeful replied that “the science in that regard is in
dispute.”
As a working molecular biologist, that was certainly a surprise to me.
In fact, the scientific community has long regarded sexual orientation –
whether gay, str... 阅读全帖

A university professor in China has estimated that 16 million women in the
world’s most populous country are married to gays.
Professor Zhang Bei-chuan of Qingdao University says the huge number of
women – equivalent to the population of the Netherlands – who have tied
the knot with gay men are struggling to cope.
Speaking to state-run China Daily, the academic said as many as 90% of gay
Chinese men marry to conform with social norms.
As of 2010, China had a population of more than 1.3 billion.

(Reuters Health) - Black men are half as likely to die at any given time if
they're in prison than if they aren't, suggests a new study of North
Carolina inmates.
The black prisoners seemed to be especially protected against alcohol- and
drug-related deaths, as well as lethal accidents and certain chronic
diseases.
But that pattern didn't hold for white men, who on the whole were slightly
more likely to die in prison than outside, according to findings published
in Annals of Epidemiology.... 阅读全帖

WASHINGTON – The 2010 census report coming out Tuesday will include a
boatload of good political news for Republicans and grim data for Democrats
hoping to re-elect President Barack Obama and rebound from last month's
devastating elections.
The population continues to shift from Democratic-leaning Rust Belt states
to Republican-leaning Sun Belt states, a trend the Census Bureau will detail
in its once-a-decade report to the ... 阅读全帖

As health care reform marks its one-year anniversary, a new Deloitte report
reveals that consumers are spending $363 billion, or 14.7 percent more, on
health care than traditionally reported in official government accounts.
This spending falls outside of conventionally-counted health care costs such
as doctors, prescriptions, hospitals, and health insurance coverage.
Demonstrating the significance of the amount consumers now spend on health
care, the additional costs captured in the new Deloitte... 阅读全帖

(Reuters) - The number of Americans newly infected with HIV remained stable
between 2006 and 2009, but infections rose nearly 50 percent among young
black gay and bisexual men, U.S. experts said on Wednesday.
New data from the U.S. Centers for Disease Control and Prevention reveal
progress since the peak of the HIV epidemic in the 1980s. But the sharp
increases in infection rates among young black men who have sex with men
show there is much more work to do, they said.
